will be Aautomatically maintained to com# pensate for evaporationj and it is also an object of the invention to provide a compact structure to accommodate the circulating;`

l heating waterand 'furnislx means whereby the expansion of the Water When heated will be accommodated.. The invention is illustrated in the accompanying; drawings and consists in certain novel features which lwill be hereinafter first fully described and then particularly pointed out in the alngiended claim. l ln the drawingsf Figure l is an elevation oit my improved heating,` apparatus;

" Fig. 2`is a plan View ot the same;

5 Fig. 3 is a sectional elevation et the expansion tank and the means for automatically maiutaining` the supply of water;

Fig. l is an enlarged detail section through the 'l'loat controlled valve, and y 'U Fig'. 5 is an enlarged detail perspective vieri oil' the valve.

In the drawings, the reference numeral l indicates a portion of a chicken house or compartment `and 2` indicates a broeder ivliiehis located Within the said house or room,fthese` parts being of` any approved construction.

In carrying` out the present '-invention, there is provided an expansion tank 3 and a reservoir or supply tanky fl which is located above the expansion tanlr and is equipijied With a discharge pipe 5 leading to a point over the top of the expansion tank whereby the Water Will be permitted to iioiv from the eration of the apparatus. Upon the discharge end of the pipe 5 is secured a valve cage 6 having a port 7 through which the Water may escape and containing; a valve 8 which is adapted to close the said port when the Water in the expansion tanlr is at the predetermined level. This valve includes a closing member '9 which is substantially circular in cross section and oit' a diameter to fit closely to or Within the port 7 when the valve is raised so that the flow of water The invention also seeks teprovide means whereby the supply oit water reservoir into the expansion tank in the op-` through the port Will be prevented. Below the closing member 9, the valve'is construetedwvith Guides l0 and 1l which have portions elftheir margins arra fredl to slid-- ably engage the walls of the valve cage and other portions, as indicated at l2, cut away to permit the 1wai-tei.' to pass the guides and tlovvinto the expansion tank. The closinuv member 9 and the guides are all. carried by a stem 13 which depends through the cage and may project below the lovver end thereo in position to be engaged by the `top ol? a float 1{vhicli is provided Within the eil? pension tank. The fioat maybe oliA any Well-known approved torni and is sruleient ly buoyant to i'olloiv lthe level et the uf'ater in the expansion tank as the same rises and falls. On the top of the iioatis provided a guide cage 15 which `lits around the lower portion of the discharge pipe 5, as shown most clearlyinliig. 1l, so that the float will be guided in :is movements and will. always be in proper operative relation to the valve. The cage 15 should have sufficient rictional engagement with the surface of the pipe and the valve cage 6 to prevent the lleat hen inpdislodged ifrom. the Vpipe and this` insult is further attained by extending1 the guide cage abovc-the-tlango idol? the val ve cane orcasing so that the down moveinoi 1 mi the 'float ivill be arrested by the upper end et the guide cage impinning upon the top ol" the said llange. lt uill now-be understood thatT When the Water in the expansion tank is at a high level, the float will be raised .so the t it will iinpinpge against thev lovver end olI the valve stem .13 and Will carry the valve into proper engageineniaavith the port so that the tloW o'lf Water into the expansion taulr will be arrested;`v Should -theulevol ot the Water in the expansion tank fall by reason of evaporation to a perceptible extentq the float will, of course, descend and the valve will then unseat throughits eivn Weight. permitting the Water to flow from the reservoir into the tank9 the flow beine; cut ell" by the return rising; movement. ot the float as the tank fills. The valve easing; is7 ot course.` provided with a stop 'i7 near its lower end to prevent the valve dropping l'rom the easing.

Cornmunicatiiugq with the interior of the expansion tank at or near the bottom thereof is a circulating pipe 18 which extents upwardly and laterally into a heating' tank 19 which is intended. to rest directly upon I the top of a heater, .indicated by dotted lines Y Water. A circulating pipe leads from the end of Athe tank A1 9- remote l from the pipelKS, and this jpipe 2O enters the brooder 2 andwwithinthe-brooder is carried back and forthto forma heating coil 21, a pipe "1:22 connecting the coil with the expansion tank neartheitop/.ef the latter.

l `Itis` thought the operation Will be readily -understoodffroin the foregoing description, taken in yconnection with vthe ,aecompanying-'drawings 1 The expansion tank be1 ing filled-"to such aheight that thefilowvcontrollin'gfeut-oft valve 8 is seated,Y the entlrecirculating system including the heating tankl9-, the pies v18, 20 and 22vand the coi'l-21- Will benlled--With Water, it being` notedjthat thetloat and val-ve are ar; ranged-to operate atapoint-ahove thefpoint "of eommunicationpfthe .ppef22-With the yexpanseion tank.v The heat from the stove will play directly upon-.the tan-k 19 andthe Wateru'insai'd tank` Will therenponbe raised in'l temperature se thatit, Willi flow' through the1pipe120 i-ntoq-theeeilllandthence back and forth toj ve'ventually''.-reach the return pipe 522 and, thereby -flow :again into the ex.- pansion-v tank.

Gradually the water in the expansion tank Will acquire a perceptible degree of heat so that a very slight consumptionl of fuel will be needed to maintain the temperature of the Water in the circulating system. The top of the tank 3 is open so that theexpansion of the water due to the heating thereof will be accommodated but some of the Water will evaporate under the inluence of the heat acquired thereby and .eventually there will be such a lowering ol the body of water in the expansion tank that the float will descend and the valve will be opened, cold Water being then permitted to enter the tank to replenish the supply. It will thus be seen that I have provided a verysimple and compact apparatus which may be operated very economically to maintain the proper temperature in the broeder and the supply of Water in the circulating system Willbe automatically maintained, it being necessary te supply additional Water to the reservoir l only at long intervalsi Having thus described the invention, I claim:

Y A .broeder heater comprising a stove arranged adjacent the brooder, a flat shallow heating tank resting directly onsthe stove, an expansion tank arranged at one side oi the heating tankk and. the stove with its bottombeloiv the plane et the heating tank; a pipe leading from -the expansion tank near 'the bottom-.thereof into. one Side ofthe heating tank, av circulating pipe deading laterally from the opposite` side ofthe heating `tank straight into the broeder7 a coil Withinthe broeder connected toand--in communication with-said pipe, and a return pipe connected to and leading` from said coil into the upper pottioneltheexpaneiotank.
